This paper proposes a reduction method for DC-link ripple current and common-mode voltage (CMV) in hybrid active neutral-point-clamped (ANPC) inverter. A Si SiC ANPC inverter has been developed recently to overcome the extremely high cost of full-SiC requires much fewer MOSFETs than while providing comparable power density. Voltage source inverters such as utilize electrolytic capacitors, which...

This paper reviews different types of capacitors and auxiliary source circuit topologies presents an introduction to control strategies used for applications reducing DC-BUS capacitance. The argues in favor replacing bulky electrolytic capacitor-supported power electronic systems with circuits. are widely grid-tied converters (rectifiers) utilized balance, voltage ripple limitation, short-term ...

A digital capacitance meter is a piece of electronic test equipment used to measure capacitance mostly of discrete capacitors. This project presents the design and implementation asynchronous digital capacitance meter using principle that when capacitor is connected across constant DC source, it charges at an exponential rate which dependent on seen by source as well resistance in circuit. In t...

Understanding the ageing mechanisms of electronic components critical avionics systems such as the GPS and INAV are of critical importance. Electrolytic capacitors and MOSFET’s have higher failure rates among the components of DC-DC power converter systems. Our current work focuses on analyzing and modeling electrolytic capacitor degradation and its effects on the output of DC-DC converter syst...

This paper proposes a physics based degradation modeling and prognostics approach for electrolytic capacitors. Electrolytic capacitors are critical components in electronics systems in aeronautics and other domains. Degradations in capacitor and MOSFET components are often the cause of failures in DC-DC converters. For example, prevalent fault effects, such as a ripple voltage surge at the powe...
